Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Romatoid artritli hastalarda alfa 1 asit glikoprotein düzeyi ile hastalık aktivitesi ve radyolojik ilerleme arasındaki ilişki
No full textRomatoid artrit (RA) kronik, inflamatuar, simetrik ve dektrüktif eklem tutulumu ve ekstra artiküler bulguları olan otoimmün bir hastalıktır. Tedavide hastalık modifiye edici ilaçlar ve biyolojik ajanlar kullanılmaktadır. Çalışmalarda RA’da gelişen inflamasyona bağlı birçok akut faz reaktanının arttığı gösterilmiştir. Akut faz reaktanlarındaki yükselme bazı çalışmalarda hastalık aktivitesi ve radyolojik hasar korele bulunmuştur. Bu çalışmanın amacı RA’lı hastalarda ve kontrol grubunda alfa 1 asit glikoprotein (AAG) düzeyini karşılaştırmak ve RA’lı hastalarda AAG düzeyinin hastalık aktivitesi ve radyolojik hasar skorlaması arasındaki ilişkiyi belirlemektir. Dicle Üniversitesi Tıp Fakültesi Hastanesi Fiziksel Tıp ve Rehabilitasyon Anabilim Dalı Romatoloji polikliniğine başvuran 56 RA’lı hasta ve 53 sağlıklı kişi kontrol grubu olarak çalışmaya dahil edildi. RA’lı hastalar muayene edilerek artrit ve hassas olan eklemleri belirlendi. DAS 28 (Diseae Activity Score) değerleri hesaplandı ve hastalık aktiviteleri DAS 28 ve VAS ile belirlendi Hastaların demografik verileri not edildi. RA ve kontrol grubunun AAG düzeyleri ELİSA yöntemiyle değerlendirildi.. RA’lı hastaların son 6 ay içinde çekilmiş olan her 2 el ve ayak grafileri değerlendirilerek larsen radyolojik hasar skorlaması yapıldı ve kaydedildi. RA’lı hastalarda AAG düzeyinin kontrol grubu ile karşılaştırılmasında istatiksel açıdan anlamlı bir fark saptandı (p=0.000). AAG düzeyi ile DAS 28 ve larsen skorlaması arasında anlamlı bir ilişki saptanmadı (p=0.371-p=0.714). Romatoid artritli hastalarda AAG düzeyinin daha yüksek olduğu tespit edildi. AAG ile düzeyi DAS 28 ve larsen skorlaması arasında ilişki saptanmadı. RA hastalarında AAG düzeyinin sebat eden inflamasyona bağlı yükselebileceği ancak bunun erozyon gelişimiyle ilişkisinin olmadığı düşünüldü. Anahtar kelimeler: Romatoid artrit, Alfa 1 asit glikoprotein, Diseae Activity Score 28, Larsen skorlamasıRheumatoid arthritis (RA) is a chronic, inflammatory and autoimmune disorder with symmetrical and destructive joint involvement and extra-articular findings. Disease-modifying antirheumatic drugs and biologic agents are used in its treatment. In studies, it is shown that a lot of acute phase reactants increase due to inflammation. Elevation of acute phase reactants are found to be correlated with disease activity and radiologic damage in some studies. Aim of this study is to compare alfa-1-acid glycoprotein (AAG) in patients with RA and control group and to determine the relation of AAG level with disease activity and radiologic damage score. 56 patients with RA who presented to Rheumatology Clinic of Department of Physical Medicine and Rehabilitation Dicle University Faculty of Medicine and 53 healthy individuals were included in this study. Demographic data of patients were recorded. Joints with arthritis and damage in patients with RA were identified with examination. DAS 28 (Disease Activity Score) values were calculated and disease activities were identified with DAS 28 and VAS. AAG levels of both RA and control groups were identified with ELISA method. Larsen radiologic damage score was evaluated and recorded by radiographies of both hands and feet of RA patients which were taken in last 6 months. In patients RA, a significant difference was detected comparing AAG level of th control group (p=0.000). There was no statistically significant relation between AAG levels with DAS 28 and larsen score (p=0.371-p=0.714). AAG levels was significantly higher in patients with RA. There was no statistically significant relation between AAG levels with DAS 28 and larsen score. It’s thought that AAG level could be risen depending persistant inflamation but it isn’t related with erosion evolution. Key words: Rheumatoid arthritis, alfa-1-acid glycoprotein, Diseae Activity Score 28, Larsen scor
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
